Due to its thermo-mechanical characteristics and material qualities, intelligent materials are distinguished from ordinary 3D printing materials by attributes of shape change. 7 The input is an intelligent substance, a hydrogel or a memory polymer. Commercial 3D printers like polyjet 3D printers are used in 4D printing technologies. 5, 6 So, a non-living thing can, over time, modify its 3D form and behaviour. Compared to 3D printing, 4D Printing technology employs sophisticated and programmable materials that add warm water, light, or heat to execute diverse functionalities. 3, 4ĤD printing is suited to manufacture innovative dosing forms and drugs, bones, ears, exoskeletons, windpipes, jawbones, eyeglasses, cell cultures, sternum cells, arteries, circulatory systems, and tissues and bodies. It has expanded its range of chemotherapeutic, self-assembly, and tissue engineering applications. 4D printing technology has many applications in various fields and has caused a significant transformation in healthcare and dentistry. The design of individual patient devices is a highly skilled and labour-intensive, multidisciplinary procedure. 1, 2 It allows us to manufacture items considerably more significant than the printer size. An item made with 4D printing technology utilising smart materials in touch with external sources such as heat, water, etc., responds and changes shape and dimensions as planned. However, as 3D printing outputs are stiff, flexible goods from 4D printing technology give way to personalising organ parts according to their look. The introduction of 3D printing has changed the health industry in numerous ways. The objective is to integrate technology and design to create self-assembly and programmable material technologies that better design, production, and performance. 4D printing is an innovative technology that uses the inputs from smart materials, and the 3D printed item becomes another structure via the impact of external energy sources such as temperature, light, or other environmental stimuli. Further, the paper identifies and discusses the significant potential of 4D printing for dentistry. Process workflow and Bio-Oriented 4D printable smart materials for dentistry are presented diagrammatically. This paper is brief about 4D printing and its printing of smart materials through 4D printing. Its applications cover medical modelling, surgical guides manufacture, prosthodontics, dentistry, orthodontics, implantology, and dentistry instruments. It is evident that 4D printing will be of tremendous value to manufacturers regarding features and advances in dentistry. Therefore, its capacity to alter shape over time is a significant advancement of 4D printing over 3D printing technologies. 4D Printing has one “D" instead of 3D Printing, and the fourth aspect is time. A significant advance in 4D printing over 3D Printing is its capacity to alter shape over time because external elements such as pressure, air, heat, water, etc., use controlled impact. Technical specialists carry out continuous research and development to increase efficiency. New developing technologies improve production speed, reduce industrial process costs, etc. In this review, we report the recent progress in the design and development of smart materials that are actuated by different stimuli and their exploitation within additive manufacturing to produce biomimetic structures with important repercussions in different but interrelated biomedical areas.Every industry need helps to modify its working style quickly with the improvement of existing technology. The term 4D printing was coined to indicate the combined use of additive manufacturing, smart materials, and careful design of appropriate geometries. In recent years, this issue has been addressed with the design and precise deployment of smart materials that can undergo a programmed morphing in response to a stimulus. However, an intrinsic limitation of this technology is that printed objects are static and thus inadequate to dynamically reshape when subjected to external stimuli. 3D printing technologies can recapitulate structural motifs present in natural materials, and efforts are currently being made on the technological side to improve printing resolution, shape fidelity, and printing speed. Nature's material systems during evolution have developed the ability to respond and adapt to environmental stimuli through the generation of complex structures capable of varying their functions across direction, distances and time.
